6 Claims. (or. 173-339) This application constitutes a division of myapplication Serial Number 155,214, filed July 23, 1937, now Patent No.2,200,332, issued May 14, 1940.

My invention relates to sockets for vacuum tubes.

One of the objects of my invention is to provide an improved contact andwiring terminal construction which will insure good contact with thetube prongs and will hold the contact and wiring terminal in positionsecurely and deflnitely.

A further object of my invention is to provide a tube socketconstruction having an improved ground connection.

Further objects and advantages of the invention will be apparent fromthe description and claims.

In the drawing in which an embodiment of my invention is shown Fig. l isa side elevational view of the socket and securing cup;

Fig. 2 is a bottom view of the construction of Fig. 1;

Fig. 3 is a fragmentary sectional view showing a contact and wiringterminal member in position in the base;

Fig. 4 is a sectional view on the line 4-4 of Fig.

Fig. 5 is an elevational view of the contact and wiring terminal member;A

Fig. 6 is a fragmentary view showing the ground connection between thewiring terminal and saddle.

Fig. 7 is a perspective view showing the saddle and ground connection.

Fig. 8 is a sectional view on the line 8--8 of Fi 9; and

Fig. 9 is a sectional view on the line 9-9 of Fig. 8.

Referring to the drawing in detail, the construction shown comprises aninsulating base I, a plurality of wiring terminal contact members 2mounted on the base, and an annular seat or saddle member 3 in which theinsulating base I is mounted for securing the base in position on thepanel 4. The securing saddle is provided with an integral tongue 5 whichmay extend downwardly and be electrically connected with one or more ofthe wiring terminal tongues 6 as shown in Figs. 1, 2, and 6.

The contact and wiring terminal member 2 may be of sheet metal shaped toprovide a contact sleeve 1 split along one side only at 8 for entongueportion 8 extending downwardly through a slot 9 at the bottom of thecontact-receiving recess III. In order to hold the contact and wiringterminal member 2 in position securely and definitely, I provide a notchll (Fig. 5) in one edge of the tongue whereby a wing portion I2 isformed having a cut edge shoulder portion which can be bent out so as tolie underneath the insulating base, as shown in Figs. 1, 3 and 4. Thewiring terminal tongues 6, after being twisted to the desired position,may be bent outwardly slightly for convenience in wiring and to bringthem into position so as to be engageable by the ground connection, ifdesired, as shown in Figs. 1, 2, and 6.

In making the wiring connection with the wiring terminal which it isdesired to ground, the

gaging the tube prong and wiring terminal bared end of the wire I3 maybe inserted through registering openings in the ground connection 5 andwiring terminal tongue 6 and secured in position by soldering, as shownin Fig. 6.

The insulating base i may be secured in the seat or saddle 3 by means ofa cupped flange portion It underlying a flange I5 on the insulating basei and by means of tongues It struck in wardly from the seat member 3 andengaging in notches in the insulating base i, thus definitelypositioning the saddle 3 with respect to the insulating base i andholding the base firmly in the saddle.

In order to enable the contact and wiring terminal members 2 to beinserted into the recesses in the insulating base, the contact-receivingportion of the recess is provided with a pair oflongitudinally-extending grooves il leading to the ends of the slot 9 sothat in assembly the edges of the tongue 6 can engage these grooves asthe contact is being slipped into position. The ground connection 5 may,if desired, be shaped to engage more than one of the wiring terminaltongues 6 as shown in Fig. 2. Also, if desired, more than one groundconnection may be provided.

As shown in Figs. 8 and 9, the sleeve portion 1 may be substantiallycircular in cross section so as properly to engage the cylindrical tubeprong and may have tongue portion l8 struck inwardly therefrom havingcut edge portions I9 extending transversely of the sleeve portion 1 forscraping engagement with the tube contact.

It will be seen that the construction shown provides a simple groundconnection and that the contact and wiring terminal members are held inposition firmly and definitely by means or the cut edge shoulder on thewing portion ll of the wiring terminal tongue 8. I

Further modifications will be apparent to those skilled in the art andit is desired, therefore, that the invention be limited only by theprior art and the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. A tube socket comprising an insulating base, pin-engaging contactsand wiring terminals mounted on said base, and means for mounting saidbase on a panel comprising a sheet metal member having an annularapertured seat portion in which said base is seated with the wiringterminals extending beyond the apertured seat portion and havingportions to be secured to said panel, said sheet metal member having anintegral tongue portion extending from and bendable relative to saidannular portion adjacent to the apertured seat and extending generallyparallel to the wiring terminals axially beyond the apertured seatportion and electrically connected with a wiring terminal to form aground connection.

2. A tube socket comprising an insulating base, pin engaging contacts onsaid base, wiring terminals extending laterally from one face of saidbase, mounting means comprising a sheet metal apertured ring-like memberin which said base is seated having integral portions to be secured to apanel, means for preventing relative rotation of said socket and mountinand an integral downwardly extending bendable integral ground terminalon said mounting terminating adjacent the end of a predetermined socketterminal and in substantial alignment therewith whereby it may beelectrically. connected thereto.

3. A tube socket comprising an insulating base, pin engaging contacts onsaid base, wiring terminals extending laterally from one face of saidbase, mounting means comprising a sheet metal ring-like member in whichsaid base is seated having portions to be secured to a panel, means forpreventing relative rotation of said socket and mounting,- downwardlyextending groundterminal on said mounting terminating adjacent the endof a predetermined socket terminal and.

in substantial alignment therewith whereby it may be electricallyconnected thereto, and a laterally extending portion on said groundterminal terminating adjacent a second predetermined socket terminal forelectrical connection thereto.

4. A mounting for a socket base having wiring terminals extendingdownwardly therefrom, comprising a centrally apertured sheet metalferrule having an axis and an internal substantially flange-like supportdisposed axially at one end of the ferrule to receive said socket andhaving in- .tegral portions for mounting on a support, and an integraldownwardly extending bendable ground terminal on said ferrule extendingaxially away from said integral portions terminating at a point such asto be adjacent the end of one of 'such wiring terminals and insubstantial radial alignment therewith.

5. A socket comprising a base, a ferrule having an aperture defined byan inner edge secured thereon for supporting .said base, a plurality ofradially positioned sheet metal wiring terminals extending axially fromthe bottom face of said base and an integral ground terminal dependingfrom and bendable relative to the inner edge of said ferrule andterminating substantially in radial alignment with a predeterminedwiring ter-; minal 6. socket comprising a base, a ferrule fixedperforation in the adjacent terminal, whereby a single conductor may beinserted through both perforations.
